SPECIFICATION forming part of Letters Patent No. 685,709, dated October29, 1901.

Application filed December 3l, 1900. Serial No. 41,750. (No model.)

To all whom, t may concern,.-

Be it known that I, EFFIE J. BRIsBEN, va citizen of the United States,and a resident of Cleveland, county of Cuyahoga, State of Ohio, haveinvented certain new and useful Improvements in Emery Wheel Dressers, ofwhich I hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in emery-Wheel dressers; and theobject of the invention is to providea 4dresser which will be simple inform and construction, compact in shape, and efticient in operation.

My invention consists in the device hereinafter described, shown in theaccompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, Fig. 2 is aface view, Fig. 3 is a longitudinal section, and Fig. t is a sideelevation, of the central tube about which the sections of the grinderare secured.

In the figures, l l are the sections,which comprise thin disk-likecentral portions 2 and crimped or uted peripheries 3, the crimpedportions projecting on either side of the disklike central portions.Awell-detnedshoulder 4. is produced at the point of juncture of each onone side of the disk, and an oblique line 5 connects the other edge ofvthe disk, with the outer edge ofthe iiute on the other side. Theprojections and obliquely-recessed lines alternate as the fiutes come toone side or the other ot the disk. These disks are sleeved upon a shortmetal tube 6, preferably formed of wrought-iron or steel, and the outerextremities of the tube are threaded at 7. Nuts or threaded washers 8are then tightly screwed upon the extremities of the tubes, two beingemployed at each end,theouter0nes servingas lock-nuts to clamp the partssecurely together. Within the tube 6 is forced the brass bushing 9,which is sleeved over the axis of the washers and tube extremities arefaced down and the extremities of the tube recessed and the innerbushing B upset to hold it securely in place. It will be observed thatthe projecting flutes upon one side of one disk engage the recessedsidesof the flutes of the nation with a central tube and threaded washfers, of a series of disks provided with flutes upon their peripheries,the said iutes projecting upon alternate sides of the disks, and theflutes upon adjacent disks interlocking with each other, substantiallyas and inthe man-1f` `ner described.

2. In van emery-dresser, the combination with a central threaded tubeand inner bushing therefor, of sectional grinders comprising disks,-sleeved over the tube, and iiutedupon their peripheries, the saidfflutesprojecting alternately beyond the sides of the disk, `and having theirrecessed faces obliquely `arranged to the edge of the disk, whereby eachflute interlocks with the corresponding ute y 8o pressedv together, andlocking-washers, uponv of the next adjacent disk when ythey are thethreaded tube on either extremity, substantially as described. 1

3. In an emery-grinder, sections, comprising disks, provided with smoothcenters centrally perforated and rexterior-crimped portions, the crimpedportions projecting on either side of the central smoothportions and`ending in well-defined shoulders, the saidA shoulders alternatingh withobliquely-sloping recesses, in combination with means for holding thesections into engagement with one another, whereby the projection on onedisk enters the recess iu the other disk and ther crimped portions :ofone disk overlap those of the adjacent disks, substantially asdescribed.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.

EFFIE J. BRISBEN.
